With some care and a bit of skill and realizing that you want to put them back in as gently as practical you can actually do a fine job of walking them back in with a block of wood and a hammer. But the key is to do this with some amount of skill and be careful to use small taps on the wood padding and to walk the cups into the frame only a couple of degrees at a time similar to the drift pin and hammer method of taking them out but in reverse.
